BC Clipboard OCR Konvorcet - Unit Conversions

Konvorcet is one of the specialised tools on clipboardocr.com, focused on distance, weight, volume and temperature conversions. Like its sibling tools (Perseus for quick OCR with tables and date/amount conversion, Confidential mode for local-only extraction, Milcheaufsnutgluten for allergen detection, Croesus Rates for currency), it starts from the same free OCR engine and adds a specific, dedicated feature on top — in this case, unit conversion.

You give it an image three ways: take a photo, paste one from your clipboard (Ctrl+V), or upload a file. The tool reads the visible text with OCR, entirely in your browser — no account, no image uploaded to any server for the standard extraction. The result appears as editable plain text, ready for you to apply a conversion, search, replace, copy or share.

It's a single switch that applies to whichever conversion category you have active. With it unchecked (the default), the converted amount is added in brackets right next to the original value, so both stay visible — for example "10 mi (16.09 km)". Checking it instead replaces the original number outright, leaving only the converted value in the text.

Choose one of the fixed pairs shown in the "Common conversion factors" table above — miles/kilometres, feet/metres, inches/centimetres or yards/metres, in either direction — and the tool multiplies every number it finds in the extracted text by that exact factor. It doesn't try to guess the unit from the text itself, so make sure you've picked the pair that matches what you're reading.

Same principle as distance: pick the pair you need — pounds/kilograms, ounces/grams or UK stone/kilograms — and every number in the extracted text gets multiplied by that fixed factor, based on internationally recognised standards (NIST, BIPM).

Volume has the most pairs available — US fluid ounces, US and UK gallons, US cups and UK pints, all against millilitres or litres, in both directions. As with distance and weight, it's a fixed multiplication factor, not a guess — pick the exact pair that matches your source unit.

Temperature is the one category that isn't a simple multiplication — Fahrenheit and Celsius are offset from each other, not just scaled. The tool applies the correct formula automatically (°F → °C: subtract 32, then multiply by 5/9; °C → °F: multiply by 9/5, then add 32), so you never have to do that calculation by hand.

Yes — the Unit converter further down the page lets you convert a single value instantly, independently of the extracted text, and isn't limited to the fixed pairs used for the image conversion above.

No. Konvorcet's conversions are all fixed, standards-based factors calculated entirely in your browser — nothing is sent to any server. The only network request is for the standard "Improve with AI" text extraction, if you choose to use it.

Area conversion covers square metres, square feet, hectares, acres, square kilometres and square miles. Pick the pair you need in the "Common conversion factors and ladders" table above — the same fixed, standards-based factors are applied automatically to every number in the extracted text, and the same units are also available in the free unit converter and the price-per-unit calculator below, so you can, for example, work out a price per square metre or per acre.

The conversion pairs used by the image extraction tool are fixed — you pick one pair (say, miles → kilometres) and it's applied to every number found in the text. The "Unit converter" further down the page is a free, any-to-any converter: pick any unit as the source and any other unit in the same category (including UK units like stone, pints or UK gallons) as the target, type a value, and get the result instantly — no image or extraction needed.

Enter a total price and a quantity with its unit (say, €250,000 for 100 m²), and the tool divides one by the other to give you the price per single unit (€2,500 per m² in that example). It works across all five categories, so you can calculate price per square metre or acre when buying property or land, price per kilogram or pound when shopping, or price per litre or gallon for fuel and drinks.

The Comparator lets you put up to four products or measurements side by side — even different pack sizes or units, like 6×330ml against 1.5L, or 50 acres against 40 hectares — and see how they compare. Add a price to any of them and the tool normalises everything to a common unit and marks the best deal per unit with a 🏆, so it's especially useful when comparing multi-packs at the supermarket, or two properties or plots of land listed in different units.

Yes. Choose the 🧩 Custom tab in the Unit converter and define a set: a base unit (say, Unit) and then each new unit as a multiple of another one (1 Box = 12 Units, 1 Tray = 6 Boxes, 1 Pallet = 40 Trays). You can keep several sets and use them in the Unit converter, the price-per-unit calculator, the Comparator and the image conversion at the top of the page — so a stock sheet or delivery note in pallets can be turned into units straight from a photo. Sets are stored only in your browser; share one with a link, or move it to another device with Export / Import JSON.
